Those calculations take into account population size and the county's age distribution, since cancer risk increases with age.

Before we get into the ranking, here's an online database that allows you to see the number of cancer deaths in each county in 2015. It also shows the percentage of all the deaths in each county that resulted from cancer. Those numbers come from the Michigan Department of Health and Human Services.

Once again, you put your cursor over a county to see the underlying numbers. (Remember: Age-adjusted mortality rate is the number of deaths per 100,000 residents.)

The caveat: The age-adjusted mortality rates are estimates, and the margin of error increases for smaller counties.

Below is the ranking of the 83 counties, starting with the counties that have the highest rate of cancer deaths.
